Re: [jsr-314-open-mirror] [jsr-314-open] [490-XmlViews] RESOLVED: Namespace and DOCTYPE
In case you guys are interested, the cases where things could get
screwed up by accident are kind of wacky:
1) Page author is prefixing is HTML tags with an identifier
2) Page author sets the default namespace to a tag handler namespace on
an html element
<f:view xmlns:html="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core" >
<html:html xmlns="http://java.sun.com/jsf/html">
<head><html:title>Title</html:title></head>
<body>
<html:h2>HTML elements ok</html:h2>
</body>
</html:html>
</f:view>
In this case, the default namespace in the output is set to
"http://java.sun.com/jsf/html" by the default tag handler when
processing the html tag, potentially blowing away the default namespace
set by the ResponseWriter.
But more complicated cases like this work the way the page author might
expect:
<f:view xmlns:h="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns="http://java.sun.com/jsf/html">
<html>
<h:head><title>Title</title></h:head>
<h:body>
<svg xmlns="http://www.w3.org/2000/svg">
<circle ... />
</svg>
<h2>HTML elements ok</h2>
</body>
</html:html>
</f:view>

That's fine

I think that they can set it on any element that uses the default tag
handler. However, they shouldn't need to pass through the HTML
namespace anyway, since the XHTML ResponseWriter should be outputting
this for them if we are actually sending out XHTML.

We agree that the multi-namespace cases can wait. The XHTML
ResponseWriter can do the right thing anyway, so there shouldn't be
any basic cases where the namespace needs to be passed through.
